BIOLOGICAL PAPERS. 247 



71. Orchelimum nitidum McNeill. 



One specimen, a female, on a small tree in my front yard, secured 

 September 7, 1904, Wichita, Kan. New to Kansas. 



72. Orchelimum nigripes Scudd. 



Very common along streams and ponds. Ten specimens, seven males 

 and three females, were taken in tall slough-grass along the Little river in the 

 city park, October 3, 1904. 



73. Orchelimum vulgare Harr. 



Common at Hiawatha and Wichita in grass and weeds during August 

 and September. 



74. Xiphidium attenuatum Scudd. 



Only one specimen, a female; taken October 3, 1904, in the city park, 

 in tall grass near the river. New to Kansas. 



75. Xiphidium ensiferum Scudd. 



One female specimen, secured by Mrs. Mary N. Isely on a bush in the 

 yard, September 15, 1904. Not reported from Kansas. 



76. Xiphidium fasciatum DeGeer. 



Reaches maturity the latter part of July. Found in tall and short 

 grass along sloughs, streams, and low ground. Taken at Atchison, Hiawatha, 

 Fairview, Wichita, Sedgwick, and Clearwater. Very variable as to wing length. 



77. Xiphidium nemorale Scudd. 



Found on the open prairies. First specimen reported from Wichita 

 July 27, 1904. Several specimens, both male and female, taken during August 

 and September. Rather rare. Not reported from Kansas. 



78. Xiphidium saltans Scudd. 



Tall grass, damp situations. Several specimens taken at Fairview 

 August 9, 1904. 



79. Xiphidium strictum Scudd. 



This is the most common member of the genus. Reaches maturity 

 early in August. Found on the open prairies and in alfalfa-fields. "On Sep- 

 tember 14, 1904, a little after sundown, in sweeping the tall grass along the north 

 side of a small alfalfa- field that had been mown that afternoon, I secured 

 seventy-six specimens of this genus, thirty-two males and fourty-four females. 

 Of the females, the ovipositor of thirty-eight measured about 22 mm. ; of the re- 

 maining six the ovipositor measured 17 mm. These measurements class the 

 first lot as X. strictum and the six as X. saltans. The males would doubtless 

 show a like proportion." (From my field-notes, September 14.) 



80. Udeopsylla nigra Scudd. 



Found under stones, clods, and boards. Nymphs taken in November, 

 March, and June. Adults were numerous in wheat- fields early in July. 



81. Ceutophilus sp. 



Found in wheat stubble in large numbers, Nickerson farm, August 30, 

 1904. Mr. Caudell writes that Professor Blatchley, to whom he referred this 

 species, regards it as close to spinosus, and also allied to blatchleyi and uhleri. 



82. Ceutophilus sp. 



One female specimen secured October 14, 1904, near a sidewalk, about 

 six p. M. Probably C. latens Scudd. 



83. Stipator nigromarginata Caud. 



One female specimen, Nickerson farm, September 30, 1904. Found in 

 a prairie pasture. New to Kansas. Mr. Caudell writes: "We have no male 

 specimens. I hope you may find some."
